Abstract

The dispersion equation for surface waves—with simple transverse exponential decay at the interface of identical biaxial crystals with a relative twist about the axis normal to the interface and propagating along a bisector of the angle between the crystallographic configurations on either side of the interface—has several solutions of which only one is physical. The selected type of surface wave is possible only for a restricted range of the twist angle, which depends on the ratio of the maximum and the minimum of the principal refractive indexes and the angle between the optic ray axes.

There appears to be a typographical error in Darinskiĭ's publication [Ref. , Eq. (10)]. To make it consistent with our results and the author's own Fig. , it should read V2/Ve2=E]-[1−3sin2phiv+cos2phiv[1+4sin2phiv(E-−1)]½]/{2[1+(E]-−1)sin]2phiv][E]-cos]4phiv−sin]4phiv]}.
